It's noted that because of the pilot's connection to their Zoid, using a Wild Blast is normally an extremely strenuous task. Pilots typically get around this by wearing a B-Proof suit, which acts as a buffer between the Pilot and Zoid, helping the bare the strain of the Wild Blast. Even so, the strain is so great that even an experienced pilot would be shocked to see someone able to use Wild Blast without a suit.
This type of blast is accessed more naturally than Machine Blast. This type of blast is quite often associated with melee weaponry, though there are some exceptions.
Evo Blast Zoids:
Beast Liger
The Machine Blast is similar in concept to the Evo Blast, but focused on the man made equipment carried by the Zoid.
